Anterior cruciate ligament injury (ACL) is a common sport injury; however, there are no data concerning dance and ACL injury. We report the incidence, injury mechanism, and clinical follow-up of ACL injury in professional dancers.
In a retrospective cohort study involving the three major dance companies in the Netherlands, by interviewing all 253 dancers who had had a full-time contract during 1991-2002, dancers with symptomatic ACL injury or past ACL reconstruction were identified and examined.
6 dancers (2 of whom were women) had had a symptomatic ACL rupture and reconstruction. Interestingly, all had been on the left side and had had a similar trauma mechanism: while dancing a classical variation they landed, after a jump, on their left leg, in the turned out position with a valgus force on their knee. There was a higher risk of ACL injury in the classical company than in the two contemporary companies. The risk of dancers having a rupture of the left ACL during a 10-year career in this classical company was 7%.
ACL injuries are not an infrequently seen type of injury in professional classical dancers, with a very specific mechanism of injury--a landing on the left leg in exorotation. More attention and prophylactic measures should be given to this specific injury mechanism.
前交叉韧带损伤（ACL）是一种常见的运动损伤；然而，尚无关于舞蹈与ACL损伤的相关数据。我们报告了职业舞者ACL损伤的发病率、损伤机制及临床随访情况。
在一项涉及荷兰三大舞蹈公司的回顾性队列研究中，通过对1991年至2002年期间所有签订全职合同的253名舞者进行访谈，确定并检查了有症状性ACL损伤或既往ACL重建手术的舞者。
6名舞者（其中2名女性）出现了有症状性的ACL断裂并接受了重建手术。有趣的是，所有损伤均发生在左侧，且损伤机制相似：在跳完古典变奏舞蹈后，她们以左腿外旋、膝关节外翻的姿势落地。古典舞团的舞者发生ACL损伤的风险高于另外两个现代舞团。在该古典舞团，舞者在10年职业生涯中左侧ACL断裂的风险为7%。
ACL损伤在职业古典舞者中并非罕见，其损伤机制非常特殊——左腿外旋落地。对于这种特定的损伤机制应给予更多关注和预防措施。
